Near to record high temperatures are forecast again Today across eastern Oklahoma and northwest Arkansas. At the same time, afternoon humidity values of 15 to 30 percent will aid in limited fire weather danger over portions of eastern Oklahoma this afternoon. Generally light winds will limit the overall fire spread rates into this evening. Southerly winds are forecast to begin increasing overnight tonight into Sunday ahead of an approaching cold front.

MONDAY...High Wind Potential. TUESDAY AND WEDNESDAY...No Hazards. THURSDAY...Very High Fire Weather Potential...High Wind Potential. FRIDAY...High Wind Potential. EXTENDED DISCUSSION... Fire weather conditions worsen Sunday with very dry fuels, low humidity, and windy conditions across eastern Oklahoma and northwest Arkansas. Southerly winds gusting up to 35 mph are anticipated during the day Sunday ahead of the cold front moving into the region Sunday afternoon. Behind the frontal passage, a wind shift out of the north with gusts of 30 to locally 40 mph into Sunday evening are forecast. These conditions combined with near to record high temperatures will create near critical grassland fire spread rates. The area of greater concern remains across northeast Oklahoma, where locally critical spread rates could develop.
